Lens and Sensor
Let me start by saying that I am not a professional photographer, just a keen amateur!
I was given a Sony A6000 some weeks ago, and then acquired the Sony18-105 f4 zoom as well as the SEL35F18. In my humble view this is a really nice camera / lens setup, and provides me with all I need for my purposes. Over the weekend I also took out my Pentax K20 and some of my legacy Pentax glass, such as a SMC135 f3.5 and SMC50 f1.8.
Much to my surprise, a visual comparison of sharpness (I use Lightroom 5.5 on an iMac) without any processing, suggests that in fact the Pentax produces images as sharp if not sharper than the Sony kit. Let me hasten to add that this does not matter to me, as for my purposes the Sony is more than adequate.
This set me wondering though whether in terms of digital technology we have reached the point where sensor technology is so well developed (and similar across various camera models) that we are effectively back to the "good old days" of film where the quality of glass was what really mattered. The issue for me is therefore not whether Pentax is better than Sony, or Canon better than Nikon, but rather one of what is the best glass for your photographic purposes.
Perhaps at some point the debates on DPReview will be as passionate about lenses as it currently is about "the best camera"?
Would love to get your perspectives also.
